LASIK (Laser in Situ Keratomileusis) is a type of laser eye surgery used to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
The procedure gently reshapes the cornea so that light focuses more accurately on the retina, improving clarity of vision.
For many people, LASIK reduces or removes the need for glasses or contact lenses in daily life.
You may be a suitable candidate for LASIK if you are at least 18 years old, have a stable glasses prescription for at least one year, and have healthy corneas without significant thinning or scarring.
People with uncontrolled diabetes, severe dry eyes, active eye infections or certain autoimmune conditions may not be ideal candidates and need detailed evaluation.
A comprehensive eye examination, including corneal topography and pachymetry, helps your ophthalmologist decide whether LASIK or another laser procedure is safest for you.
LASIK is usually performed as a day-care procedure and typically takes about 15–20 minutes for both eyes.
First, numbing eye drops are applied so you remain comfortable while staying awake and able to follow simple instructions.
A thin corneal flap is then created, most commonly with a femtosecond laser, and gently lifted to expose the underlying corneal tissue.
An excimer laser is used to reshape the cornea by removing microscopic layers according to your customized treatment plan; the flap is then repositioned, where it adheres naturally without stitches.
LASIK can provide rapid visual recovery, with many patients noticing clearer vision within hours to a day after surgery.
The procedure is highly precise, guided by detailed corneal measurements and advanced laser platforms designed to optimize visual quality and contrast sensitivity.
For suitable candidates, LASIK offers long-lasting correction of refractive error, allowing greater freedom in work, sports, and daily activities.
Like all surgical procedures, LASIK carries some risks and potential side effects.
Common temporary effects include dry eyes, mild discomfort, glare, halos around lights, and fluctuating vision during the early healing period.
Less commonly, under-correction, over-correction, infection, or corneal ectasia can occur, which is why careful pre-operative screening and post-operative follow-up are essential.
Your surgeon will discuss these risks in detail and explain alternative options, such as PRK or SMILE, if LASIK is not the best choice for your eyes.
Most patients can return to routine non-strenuous activities within a day or two, although the eyes continue to heal over several weeks to months.
You will be prescribed antibiotic and lubricating eye drops, asked to avoid rubbing your eyes, and advised to protect them from dust, water contamination, and bright light in the early phase.
Follow-up visits allow your ophthalmologist to monitor healing, manage dryness, and confirm that your vision is stabilizing as expected.
Seek timely evaluation to improve your vision and reduce dependence on glasses or contact lenses. Benefit from expert LASIK treatment at Chopra Nethralaya to achieve clearer, more comfortable eyesight.
